SPRING-WHEEL.

Specification of Letters Patent.

Application filed March 8, 1911.

Patented Aug. 29, 1911. Serial No. 613,036.

To all whom it may concern:

Be it known that I, ENos A. WALL, a citizen of the United States,residing at Salt Lake City, in the county of Salt Lake and State ofUtah, have invented certain new and useful Improvements in Spring-Wheels, of which the following is a specification.

My invention relates to spring-wheels.

The object of the invention is to provide a spring wheel which shall besimple in construction, efficient in operation, and in which the weightborne by the Wheel will be as evenly distributed as possible. Thisobject I accomplish by the construction shown in the accompanyingdrawing, in which Figure 1 is a sectional side elevation of a wheelembodying my improvements. Fig. 2 is a cross-section on line 22 ofFig. 1. Fig. 3 is a detail perspective of one of the outer rim-sections.

A designates the hub from which radiate spokes, a, connected at theirouter ends by a circular metallic band A, provided on its outer sidewith clips or fastenings a. The outer rim of the wheel is formed of aseries of flanged metallic plates B, spaced apart at their ends andprovided between their ends in their outer faces with sockets b, andwith clips Z).

G, C designate transversely arranged coiled springs; the ends 0, 0 ofthe spring 0 diverging and engaging respectively the clips 0; and 6,while the diverging ends 0', c, of springs G, project oppositely to theends 0, c, and engage other clips a, b. The upper extremities of eachpair of springs engage the clips 3), at the ends of each plate or outerrim section B, so that there is a pair of springs under every plate orsection.

D, is the rubber tire extending around the flanged plates B, andprovided on its inner side with integral studs or projections d, whichenter the sockets Z), in the outer sides of the plates B and so preventthe tire from creeping. These interlocking studs and sockets d, I),also, in holding the tire D from traveling, cause it to be subjected totensile strain between the plates B, B, and this adds greatly to theresiliency of the wheel and to the equal distribution of the weightborne thereby.

It will be seen that the load borne by the wheel will be supported byall the springs and that the stretching of the tire D, will assist thesprings materially.

What I claim is:

A resilient wheel comprising a rim, an

- outer sectional rim formed of a circular series of socketed plates,springs transversely coiled between their ends and connected at theiropposite diverging ends to the inner wheel member and opposite ends ofthe said plates, respectively; a pair of such springs to every outersection with their coils ex tending parallel to the axis of the wheeland in horizontal alinement,and a rubber tire carried by the saidsections and having studs entering said sockets.

In testimony whereof I aflix my signature in presence of two witnesses.
